MFMA Turns to RH Concrete Moisture Testing as New Standard. Recently, Maple Flooring ManufacturerÂ’s Association (MFMA) announced that effective October 1, 2011, it will only recognize Relative Humidity (RH) testing as the standard for measuring moisture levels in concrete slabs.

The innovative new Rapid RH® 4.0 Easy Reader from Wagner Electronics is designed to make taking relative humidity readings on any job site fast and accurate for inspectors, contractors and flooring installers.

The new Touch-n-Sense™ technology means the Easy Reader goes to work instantly when inserted into any Wagner 4.0-version Smart Sensor. On contact, the Easy Reader will turn on, take the reading and can be immediately removed from the test hole.

Wagner Electronics, the maker of moisture meters for the flooring industry, announced that Steve Raisner, training coordinator of the flooring program from which INSTALL Philadelphia mechanics are taught, will serve as the company’s lead instructor in a new national training initiative.

In a newly released webinar, Howard Kanare of the Portland Cement Association’s laboratory presents breakthrough scientific data that seriously challenges what we have believed regarding traditional methods for moisture testing of concrete slabs.

The importance of the 40% depth requirement (for a slab drying from one side; 20% if from two sides) for determining a slab’s internal relative humidity was clearly shown in mid-90’s work done by Dr. Göran Hedenblad at the Technical University of Lund in Sweden.
